A new cell factory for high-efficiency production of ectoine

已发布 08 十一月, 2021

A study published in the KeAi journal Green Chemical Engineering, has reported the biotechnological construction of an efficient ectoine cell factory based on E. coli BL21(DE3). Using metabolic engineering, researchers synthesised the ectoine with the E. coli, using glucose as the sole carbon source. By reconstructing the ectoine synthetic pathway, and enhancing the biosynthesis of ectoine precursor in E. coli, a high level of 60.7 g/L of ectoine was produced using a fed-batch fermentation approach.

Existing product standards for off-grid solar systems could prove a barrier to India’s energy transition

已发布 03 十一月, 2021

Indian product standards for off-grid solar systems are acting as barriers to the country’s energy transition. Such barriers can increase the costs for manufacturers of complying with the various standards’ testing and certification procedures, while the variation in product service levels can result in mistrust among consumers.

Mapping the impact of tiered pricing reform on China’s residential electricity use

已发布 01 十一月, 2021

According to author Xiumei Yu: “The results of the paper have several policy implications. The fact that the average residential electricity use was reduced by the tiered pricing reform shows that this kind of reform can encourage residents to reduce their electricity use. In addition, our results suggest that policy intensity can be a powerful tool to guide residents to use electricity more efficiently.”

New NLP model improves stock market predictions

已发布 22 十月, 2021

A group of researchers at the Research Center for Social Computing and Information Retrieval at China’s Harbin Institute of Technology have constructed a model that can synthesise these multiple data sources and the various forms of data they contain. Study results, published in the KeAi journal AI Open, show that their model achieves a higher AUC (area under the precision-recall curve) score than existing models.

Peer Review Week 2021 – KeAi reviewers share their thoughts on this year’s theme ‘identity’

已发布 20 九月, 2021

At KeAi, we are enormously grateful to the tireless efforts of our reviewer community, who have not only helped us enhance the scope and quality of our existing journals, but also launch new titles. So, we asked them for their thoughts on reviewing and this year’s PRW identity theme.

Scientists develop AI to predict the success of startup companies

已发布 14 九月, 2021

In a bid to identify which companies are more likely to succeed, researchers have developed machine-learning models trained on the historical performance of over 1 million companies. Their results, published in KeAi’s The Journal of Finance and Data Science, show that these models can predict the outcome of a company with up to 90% accuracy. This means that potentially 9 out of 10 companies are correctly assessed.

Enriched bicarbonate electrolytes show promise in combatting CO2 and the greenhouse effect

已发布 01 九月, 2021

CO2ER, the electrocatalytic reduction of carbon dioxide (CO2), offers an ideal route for mitigating the greenhouse effect and achieving green CO2 cycling. In recent years, most studies on CO2ER have focused on the intrinsic performance of the catalysts. While bicarbonate - an electrolyte or negatively-charged ion that is used by the body to help maintain its pH balance - is commonly used in CO2ER, a group of researchers from China set out to explore its role and behaviour in more detail.
